Month: December 2016

This interactive presentation contains the latest oil & gas production data from 18417 horizontal wells in the Eagle Ford region, through August.

As you can see, oil production in the Eagle Ford has declined very steadily over the year, and reached a level in August last seen 3 years earlier.

If you switch to product “gas”, you’ll see that gas production has also declined recently, although less sharp.

In the “Well quality” tab, we can see that production profiles have on average not changed much in recent years, apart from an early gain in the first year on production. The bump in production (enlarged due to the logarithmic scale) in the 2011 vintage is likely caused due to a refracked older well.

After selecting the “Top operators” tab, you’ll notice that the top 5 operators have all reduced production during the previous 1.5 year. However, the decline in output from the other operators is larger.

The new ‘Advanced Insights’ presentation is displayed below:

This first overview shows the path that wells from a certain period are taking towards their ultimate return. The wells are grouped by the quarter in which they started. By clicking through the legend, you’ll get a better idea of how these profiles have changed over time.

Also here you can switch to gas (using the ‘product’ selection at the top right), to see towards which ultimate gas return these wells are heading.

Note that this data also includes wells that are located in other formations than the Eagle Ford (e.g. the Austin Chalk). To filter those out, you can use the “formation” selection, to only include Eagle Ford wells.

I now have the detailed location data for most wells in Texas, so the maps in the next couple of views display quite accurately the location of the wells in the Eagle Ford region, and how well productivity is geographically distributed.

For a more detailed description of these new overviews, please visit the first version of this advanced presentation for ND available here.

A new ‘Gas Oil Ratio’ dashboard has been added to the end, which displays how this gas/oil ratio has changed over time in this basin.

As Ohio has not yet released Q3 production, I decided to first post updates on the Eagle Ford, and the Permian (planned for coming Wednesday).

Production data is subject to revisions, especially for the last few months in Texas. For this presentation, I used data gathered from the following sources:

Texas RRC. Individual well profiles are estimated from well status & lease production data, as this data is not provided by the RRC.

====BRIEF MANUAL====

The above presentation has many interactive features:

You can click through the blocks on the top to see the slides.

Each slide has filters that can be set, e.g. to select individual or groups of operators. You can first click “all” to deselect all items. You have to click the “apply” button at the bottom to enforce the changes. After that, click anywhere on the presentation.

Tooltips are shown by just hovering the mouse over parts of the presentation.

You can move the map around, and zoom in/out.

By clicking on the legend you can highlight selected items, and include or exclude categories.

Note that filters have to be set for each tab separately.

The operator who currently owns the well is designated by “operator (current)”. The operator who operated a well in a past month is designated by “operator (actual)”. This distinction is useful when the ownership of a well changed over time.

If you have any questions on how to use the interactivity, or how to analyze specific questions, please don’t hesitate to ask.
